我尝试使用页面中的Selenium Grid Extras:https://github.com/groupon/Selenium-Grid-Extras
我设法在我的私人计算机上成功使用它。我运行了命令" java -jar Selenium-Grid-Extras-Jar.jar"在配置(https://ibb.co/j4wZPH)后,我能够通过转到地址http://localhost:4444/grid/console来查看节点:
但是当我尝试在公司笔记本电脑上执行相同的过程时,我收到错误消息:
我将附上此错误的完整日志:

当我去:http://localhost:4444/grid/console时 - 我看到了这一点:
我试图弄清楚为什么我会收到此错误并找到答案(https://stackoverflow.com/a/42187314/7967616)Selenium Grid没有任何节点可用于具有所需功能的浏览器。
但在配置过程中,我为Selenium网格节点设置了PORT 5555,它可以在我的私人笔记本电脑上运行。我在互联网上找不到答案,所以我的预感是该PORT存在一些问题,但我不知道如何检查这个问题。
任何人都有类似的问题或问题,或者可以帮我解决这个问题? 将不胜感激任何帮助。
EDITED
ChromeDriver版本为2.38(最新)
Chrome浏览器版本为66.0.3359.117(实际)
我确保自己拥有ChromeDriver和浏览器的最新版本。
答案 0 :(得分:1)
解锁防火墙中的selenium extras,hub和node ports,然后它就能正常工作
答案 1 :(得分:0)
此错误消息......
Caused by: org.openqa.selenium.WebDriverException: Error forwarding the new session Empty pool of VM for setup Capabilities {browserName: chrome, version: }
...表示 ChromeDriver 无法启动与WebClient的有效连接,即 Chrome 浏览器。
如果没有 ChromeDriver 和 ChromeBrowser 版本控制信息,您使用的二进制文件之间似乎存在版本兼容性问题,如下所示:

。答案 2 :(得分:0)
我的队友帮我解决了这个问题。我不得不在Windows Defender防火墙中解锁端口。
重复这个过程但是:
重新启动系统并再次设置Selenium Grid Extras。它奏效了!
